LAMP AND SHADE HOLDER.

SPECIFICATION forming part of Letters Patent No. 471,286, dated March22, 1892.

Application filed m 15, 1891.

To all whom it may concern:

Be it known that we, WALTER S. A'rwoon and HENRY H. ASHENDEN, citizensof the United States, residing at Waterbury, in the county of New Havenand State of Connecticut, have invented an Improvement in Lamp and ShadeHolders, of which the following is a specification.

Lamp -shade holders have hitherto been made of a ring capable ofexpansion or contraction, so thatthe lamp can be introduced from belowand then grasped by closing the ring.

In the present improvements the ring is made expansible and can beclosed by a toggle action, and the ring is provided Withsupports for thelamp-shade, in order that the shade may be permanently supported fromthe expansible ring whether it is open for the reception or removal ofthe lamp or whether it may be closed to hold such lamp.

In the drawings, Figure 1 is an elevation of the lamp-holding ring and apart of a shade. Fig. 2 is a plan View of the same. Fig. 3 is a partialelevation with the parts of the toggle closed.

The ring A is made open and preferably slotted at 2 3 for the receptionof the studs or rivets 4 5. These become guides to keep the partsparallel as the ring is expanded or contracted, and upon the pivot 4 weconnect the ver is pivoted at 7 to the link 0, which link at itsopposite end is pivoted at 8 to the ring near the opposite end thereof.Hence by turning the thumb-lever B in one direction the parts assume theposition represented in Fig. l and the link Oand thumb-leverB slide therespective ends of the ring A, so as to open such ring or expand it to asufficient size, as shown by dotted lines, Fig. 2, for the lamp to beintroduced from below up through the ring, and when the thumb-lever B isturned in the other direction and assumes the position represented inFig. 3 the toggle action of the thumb-lever B and link 0 draws the endportions of the ring to lap them farther on each other and contract thering and $erial No. 399,542. (No model.)

cause it to grasp the lamp after the latter has been inserted, and bythis contraction we are enabled to open or close the ring withreliability, and the parts are strong and there is no risk of the ringspringing open when in use and dropping the lamp.

Around the ring at about equal distances apart there are loops D, intowhich are introduced the lower ends of the shade-holding arms E, andthese arms are of proper size and shape and spread more or lessoutwardly from the ring to receive the lamp-shade, which lamp-shade maybe of porcelain or other material. We have shown part of a shade at F.These shade-holding arms E may be lifted out from the sockets or loops Dwhen the lampholding ring is used without the shade.

The ring A is to be supported in any suitable manner. We haverepresented the bracket G as attached to one side of the expansible ringA, which bracket is received by a pivot or socket H, screwed in anysuitable place, such as upon a door-frame or other article.

We claim as our invention-= Y 1. The combination, with an expansiblering, of a lever and link pivoted to the ring near the ends thereof andadapted to be turned for expanding or contracting the ring and a supportconnected with the ring, so that the lamp can be held or removed fromposition, substantially as set forth.

2. The expansible ring slotted near the ends and provided with guides,in combination with the thumb-lever pivoted near one end of the ring anda link pivoted to the thumb-lever and to the ring near the other endthereof for expanding or contracting such lamp-holding ring,substantially as set forth.

3. The combination, with a bracket-arm, of an expansible ring fastenedto the bracketarm and provided with guide-studs and a thumb-lever andlink pivoted together and to the ring near the ends thereof,substantially as set forth.

4. The combination, with the bracket, of an expansible ring connectedwith such bracket, and means for securing the ring when con= tractedaround the lamp, and shade-holding arms extending up from the ring,substantially as specified.

5. The combination, in a lamp-support of an expansible ring, socketsupon such ring, shade-holding arms received into such sockets, and alever and link pivoted together and to the expansible ring near therespective ends thereof for expanding or contracting such ring,substantially as set forth.

Signed by us this 11th day of July, 1891. W. S. ATWOOD.
